This invention is a division of my application Serial No, 386,260, filed June 3, 1920,

- for roofing attachments, and relates particularly to means for securing "the edges t overlapping areas of flexible roofing material, and has for its object to provide a cheap efficient and readily applied attaching} means of sheet metal, which maybe applied to the sheet roofing at the time of applying building,

the roofing to a building, or a-tthe time of the roofing for application to a preparing andflwhich'in one iorm will be v self-attaching to the structure to which the roofing material is to be applied.

The invention proceeds upon the principle of forming a piece of sheet metal, including a base, with anchoring means presented from the underside of the base, attaching the device to serve as a roofing cleat, and having its anchoring means as well as the openings in the roofing material formed thereby, completely housed and protected from the weather. The anchoring means in one form being, to be driven into the surface of the struc ture which is to receive the roofing material, or, as in another, thru an overlapped roof- .ing sheet to serve as a means for uniting the sheets, and whollyseparate from the feature of anchoring the roof to the building structure.

Two different embodiments of the invention are shown in the accompanying drawing by way of illustration. In said drawing Figure 1 is a perspective view of one form of cleat; Figure 2 is a view in side elevation, illustrating application of the form shown in Figure 1; Figure 3 is a perspective view of a modified form of cleat; Figure 4 is a perspective view of still another modified'form; Figure 5 is a view in horizontal section illustrating the application of the form shown in either Figures 3 or 4; Figure 6 is a perspective view illustrating the application of that form of cleat shown in Figures 3 to 5 inclusive.

Referring now to the drawing in detail, 1 represents the base of the cleat, which according to Figures 1 and 2 comprises a relatively fiat top portion, with relatively short weathering aprons 2 and 3 formed on I the sides thereof, the apron --2' is simply a downwardly turned ordefle'cted portion of the top -1-, whereas the apron -2- is a deflected portion of the top 1- which is as above stated, presented in position turned downwardly and thenbent upon" itself, with the underlying part lying flush against'the underside of the top and terminating in anchoring means, con1.

prisingspurs or the like 5 These spurs are formed by stampingfor otherwise cutting the edge of the under-turnedapromto leave downwardly presented J impaling terial, the cleat is mount'ed'upon'the "sheet A and with the spur '-'-5- driven. into the v points, as shown in. Figurefl, with A andB .lfepresentlng the overlapping roofing niasheet A and, into the sheet B, thus locking the two sheets together. The aprons 2and 3 will bite into the material of the sheet A to form a watertight joint, so as to com pletely cover the spur 5- and the opening which it makes in the sheets A and'B.

In Figure 3 the base 1 is made with a short apron 2 withthe opposite end of the' base turned under, as at 3 and terminating i with spurs 5 In this form theapron -3 is omitted. V I I The form shown in Figure 4: is identically the same as Figure 3, excepting that the apron 2 is somewhat longer than the apron 2 This, of course, is not a, material difference and is only arranged in order to provide for difierent thicknesses of the sheets A and B. In any event, for either the form shown in Figure 3 or Figure 4 the spur 5 will penetrate not only sheet A of the roofing material, asin Figure 2, but also passing completely thru sheet B and into the building structure to which the roofing is to be applied. Instead ofbeing raised above sheetA, as indicated in the form shown in Figure 2, the base 1 lies flush with the surtace of the sheet A, excepting for the double thickness 3 made by turning the end of the base under, which, of course, leaves a space between the surface of the sheet A and the underside ofthe base in front of the spur 5 which space is equal to the thickness of the underturned portion 3 The cleat is presented near the edge of the sheet A so that the apron f2, overlaps the end of the sheet and protects the space between the sheets against the weather. In other words, although the overlap is made in the directionof the watershed, should wind blow the water back over the roof,- as it often does,

the overlap in this respect. Thisalso applies to the relatively narrow weathering apron the weathering apron 2 thoroughly protects tected by the base of theclea t, as well as the opening which it makes in the sheets A and manner.

2. The anchoring spur 5 is completely pro- B, so that the connection is practically waterproof.

In producing these cleats I can turn them out in a very simple andinexpensive manner, for instance by stamping. They are ex ceedingly convenient to apply and serve their intended purpose in a most efficient I claim 1. In a roofing attachment, a sheet metal spur projecting from said underlap and protected by the overlying portions of the base.

2. In a roofing attachment, a sheet metal i base having a portion thereof folded upon itselfto provide an underlap, an anchoring spur projecting from said underlap and protected by the overlying portions of the base,

' thefolded portion of the attachment being deflected from the plane of the base toprovide a weathering apron.

3. In a roofing attachment, a sheet metal base having a portion-thereof folded upon itself to provide an underlap. an anchoring spur projecting from said underlap and protected' by the overlying portions of the base, the folded portion of the attachment being deflected from the plane of the base to provide a Weathering apron, said base also having its edge opposite the fold deflected to form a second Weathering apron.

4:. In a roofing attachment, a sheet metal base having a portion thereof folded upon itself to provide an underlap, and a nailing spur projecting from said underlap, and protected by the overlying portion of the base, said base having its edge opposite the fold 'deflected'to form a weathering'apron.
